He lay there stabbed to death for several hours before anyone noticed him.

Then a 911 call came in to report a body on a Fontainebleau street in northwest Miami-Dade before noon Saturday.

Now Miami-Dade police detectives are trying to find out who killed 24-year-old Yader Montiel-Guillen at 2:30 a.m. Saturday.

“We really need the community’s help,” said Argemis Colome, a Miami-Dade police spokesman.

Friends and family took to Facebook to mourn their loss.

Jose Luis Montiel-Guillen, who said Yader was his big brother, posted a photo Sunday morning of the two together. Nearly 50 people commented.

“You dont know how sorry I am Jose,” said Cristhian Marcela Gutierrez Ampie in Spanish. “We studied together in elementary school and he was a great guy.”

After being asked what happened to his brother, Jose Luis Montiel-Guillen replied on Facebook in Spanish: “Lamentable death. He was assassinated.”

Police are asking anyone with information to call Miami-Dade Crime Stoppers at 305-471-TIPS (8477).
